Elizabeth was born on 21 April 1926, the first child of Prince Albert, Duke of York (later King George VI), and his wife, Elizabeth, Duchess of York (later Queen Elizabeth The Queen Mother). Her father was the second son of King George V and Queen Mary, and her mother was the youngest daughter of Scottish aristocrat Claude Bowes-Lyon, 14th Earl of Strathmore and Kinghorne. She was delivered at 02:40 (GMT)[1] by Caesarean section at her maternal grandfather's London home, 17 Bruton Street in Mayfair.[2] The Anglican Archbishop of York, Cosmo Gordon Lang, baptised her in the private chapel of Buckingham Palace on 29 May,[3][b] and she was named Elizabeth after her mother; Alexandra after her paternal great-grandmother, who had died six months earlier; and Mary after her paternal grandmother.[5] She was called "Lilibet" by her close family,[6] based on what she called herself at first.[7] She was cherished by her grandfather George V, whom she affectionately called "Grandpa England",[8] and her regular visits during his serious illness in 1929 were credited in the popular press and by later biographers with raising his spirits and aiding his recovery.[9]

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

The Great Wall of China, one of the most famous structures in the world, was built over several dynasties primarily to protect against invasions and raids from nomadic groups. The earliest walls are believed to have been built as early as the 7th century BC, with the most well-known sections constructed during the Ming Dynasty (1368-1644). Stretching over 13,000 miles, the Wall consists of various walls and fortifications. Construction materials included earth, wood, bricks, and stone, and techniques varied depending on the geography and resources available in different regions. The Wall also facilitated border control, allowed the imposition of duties on goods transported along the Silk Road, and served as a means of military signaling and troop transportation. Over time, sections of the Wall fell into disrepair, but it remains an enduring symbol of China’s strength and history.
